Abstract

A comparison of the results of two different experimental methods of measuring the neutron absorption and fission cross sections for 235 Pu is made.These measurements mere normalized at thermal energy and extend to 200 keV.The ratio of the neutron capture to fission cross section for 239 Pu derived in these two experiments is shown to be in good agreement.
